I’m definitely trying to find that balance of low RR and comfort. On my TCR I run 28c 5K TL at 70 and find that to be my personal sweet spot. Yes if I went higher I’d decrease RR but then the comfort on badly paved roads (which is 95% of where I ride) starts to suffer. But that’s a 28c vs the 25c on my S3 which is the largest that frame will accept. I’m at the halfway point of my daily ride (aka Blue Bottle Coffee) and all far I’m really liking the 25c ENVE 70psi combo. Significantly more comfortable than the 80psi I ran the other day but still feels fast. I’ll experiment with maybe 65 in a day or two but 70 may be the sweet spot. Which would make it easy for me to remember so I can run either bike at the same pressure.
